Widia 5710590 Indexable Square-shoulder End Mill VSM490

Product Description

The WIDIA 5710590 is an indexable square-shoulder end mill built on the VSM490-15 platform, designed for milling, pocketing, and slotting operations in general-purpose machining environments. The cutter body is steel construction with a 1-inch Weldon Flat shank and accommodates two XNGU15 series inserts secured by screw clamping. It delivers a maximum depth of cut of 1.75 inches, a 90-degree lead angle, and a right-hand cut orientation. Coolant-through capability is supported via a 0.2362-inch coolant hole diameter. Maximum spindle speed is rated at 26,300 RPM. This tool is installed and used by machinists and tool-and-die technicians working on CNC mills and machining centers.

The 5710590 is suited for square-shoulder milling across a broad range of workpiece materials, consistent with its universal primary workpiece material rating. Typical applications include face milling, shoulder milling, pocketing, and slotting on ferrous and non-ferrous stock. The two-flute spiral configuration and negative axial and radial rake geometry (-8 degrees axial, -20 degrees radial) make it well-matched to general-purpose production and job-shop environments where insert indexability reduces tooling downtime.

Key Features

• Coolant-through design with 0.2362-inch coolant hole for chip evacuation and heat management
• Screw-clamped insert holding for secure seating under aggressive cutting conditions
• Rated to 26,300 RPM for high-speed CNC applications
• Multi-use tool designation supports milling, pocketing, and slotting without tool change

Compatibility

Compatible with XNGU15 series indexable inserts. ISO designation VSM490D100Z02W100XN15. Designed for use in standard Weldon Flat shank toolholders accepting a 1-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists familiar with CNC toolholding systems. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter body. Seat the Weldon Flat shank fully into the holder and torque set screws per the toolholder manufacturer's specification. Inspect insert seating surfaces and clamp screws for wear or contamination before each insert index.
